Abstract
The invention relates to a hydraulic oil path for controlling a reverse gear of a six-speed automatic transmission. The hydraulic oil path comprises an oil pump and a reverse gear execute component, wherein an electromagnetic valve and a pressure controlling valve are additionally arranged between the oil pump and the reverse gear execute component; an outlet of the oil pump is divided into two pathes respectively connected with the electromagnetic valve and the pressure controlling valve through a pipeline I; the electromagnetic valve is connected with the pressure controlling valve through a pipeline II; the pressure controlling valve is connected with the reverse gear execute component through a pipeline III. The hydraulic oil path for controlling the reverse gear of the six-speed automatic transmission is simple in structure and rational in design; with adoption of a simple oil pressure self-regulating scheme, oil pressure is controlled within a comparatively low range with a stable performance, meanwhile, purposes of using a complex control program and enhancing the reverse gear execute component are avoided, thereby reducing development cost of parts and cost of matching and calibration of the control program, and shortening a development cycle of a product.
Description
Technical field
The invention belongs to the automotive transmission technical field, particularly a kind of 6 gear transmissions control hydraulic circuit that reverses gear.
Background technique
At present, the shift impact that occurs in the automatic gear automobile shift process is a great problem of puzzlement automatic transmission.Especially in the operating mode of reversing gear, when reversing gear in the oil circuit oil pressure excessive, impact sense in the shift process obviously, itself be a kind of very abominable operating mode to speed changer hardware, shorten the speed changer life-span, driver's driving sense is also very poor.
Summary of the invention
The objective of the invention is to overcome the deficiency that exists in the above-mentioned technology; Provide a kind of simple in structure, reasonable in design; Reduce the shift of transmission hydraulic pressure; Reduce impact, prolong the speed changer life-span, 6 gear transmissions that improve the shift of transmission quality control hydraulic circuit that reverses gear shifting element.In order to achieve the above object; The technological scheme that the present invention adopts is: it comprises oil pump and reverses gear executive component; At oil pump with reverse gear between the executive component to increase solenoid valve and pressure controlled valve are set; Oil pump outlet is divided into two through pipeline I and connects solenoid valve and pressure controlled valve respectively, is connected through pipeline II between solenoid valve and the pressure controlled valve, and pressure controlled valve is connected through pipeline III between the executive component with reversing gear.Advantage of the present invention is: simple in structure, reasonable in design; Adopt simple oil pressure self-control scheme; Oil pressure is controlled at low scope, and stable performance, avoids the use of complicated control program and the reinforcement executive component that reverses gear and realize; Thereby reduced the cost of part development cost and control program matching and calibration, shortened product development cycle.
Description of drawingsFig. 1 is a structural representation of the present invention.
EmbodimentBelow in conjunction with accompanying drawing embodiments of the invention are described in further detail.Can know by Fig. 1; It comprises the present invention oil pump 1 and reverses gear executive component 2; At oil pump 1 with reverse gear between the executive component 2 to increase solenoid valve 3 and pressure controlled valve 4 are set; Oil pump 1 outlet is divided into two through pipeline I 5 and connects solenoid valve 3 and pressure controlled valve 4 respectively, is connected through pipeline II 6 between solenoid valve 3 and the pressure controlled valve 4, and pressure controlled valve 4 is connected through pipeline III 7 between the executive component 2 with reversing gear.Described pressure controlled valve 4 is made up of valve body 8, spool 9 and spring 10, and spool 9 is arranged in the valve body 8 with spring 10, and spring 10 is installed in spool 9 ends.Working principle of the present invention is: can be known that by Fig. 1 the present invention acts on pressure controlled valve 4 left ends through pipeline II 6 oil pressure that solenoid valve 3 adjusts, and spool 9 is applied power to the right; Spring 10 compressions apply pressure to the right to spool 9; Pipeline III 7 oil pressure affact on the executive component 2 that reverses gear as output oil pressure, carry out the control of reversing gear, and pipeline III 7 oil pressure also can act on spool 9 left ends simultaneously, and spool 9 is applied pressure to the right.After pipeline III 7 oil pressure became greatly, spool 9 suffered pressure to the right became big, and spool 9 is slided to the right, and so, the port that pipeline I 5 leads to pipeline III 7 can diminish, and too high pipeline III 7 oil pressure are reduced.It is thus clear that it is this hydraulic circuit structure can be carried out self-control to oil circuit itself, stable to a less oil pressure scope.Thereby reduce impact, prolong the life-span of the executive component that reverses gear, promptly prolong the speed changer life-span, reduce shift impact simultaneously, improve the shift of transmission quality the executive component that reverses gear.
